write a short note on thermoplastic and thermosetting plastic
Answers
Explanation:
A thermoplastic is a material, usually a plastic polymer, which becomes more soft when heated and hard when cooled. Thermoplastic materials can be cooled and heated several times without any change in their chemical or mechanical properties. When thermoplastics are heated to their melting point, they melt to a liquid.
A thermosetting plastic is a polymer that irreversibly becomes rigid when heated. Such a material is also known as a thermoset or thermosetting polymer. ... Heat provides energy for chemical reactions that increase the cross-linking between polymer chains, curing the plastic.
Answer:
both have different properties but main property is this that thermoplastic can be re-melted into liquid but thermosetting plastic have definite solid state
